2 Claims.

This invention relatesto-a carton for containing small fragile articles such-as eggs, Christmas ornaments and the like, and to a method, of making the same.

Objects of the invention are to provide a durable, highly protective, inexpensive, and easily set up cartonwhich can be stored and shipped flat and rapidly utilized by the packer. In accomplishing these objects, I provide a formv of construction which uses as much astwenty-five per cent less stock than those commonly used, yet which provides adequate safety for the contents. I-Iitherto, it'has been common to'sacriflce one advantage for the other.

The nature and purpose of the invention will best be understood from the following description.

in conjunction with the accompanying drawings, in which:

Fig. l is a View in perspective, partly broken away, of a carton which has been set up ready to receive its contents;

Fig. 2 is a plan view of a carton blank.

Figs. 3, 4, 5, 6 and '7 are edge views of the blank showing progressive steps taken in forming the carton.

Fig. 8 is a perspective View of a portion of a carton before its end panel has been folded up into place.

Fig. 9 is a similar View showing` the end panel folded up with its locking tabs partly engaged.

Fig. 10 is a fragmentary perspective view showing the cover locked in place.

In the preferred form of the device shown in the drawings, a sheet of stock S is cut to provide top locking tabs I, end locking tabs 2, lateral dividers 3, bottom slots 4, and end tab locking slots 5. Subsequent folding of the blank will be facilitated by crimping along predetermined fold lines, which are indicated at a-a, b-b, c c, d-d, e-e, f-f, g-g, h-h, 2-1, j-y', k-k and Z-l (Fig. 2). These fold lines divide the blank into a series of panels and dividers. There is a top locking panel IU which carries the tabs I, carton top II, rear wall I2, bottom I3, front wall I4, lateral divider panel I5, interior longitudinal wall I6, additional bottom panel I'I, glue panel I8, lateral divider panel I9, and interior longitudinal wall glue strip panel 2D. Protruding from each side edge of the blank are end panels 2I and 22.

Panels I and I9 are cut, as aforesaid, to form a series of tabs or dividers 3 which, on being bent downwardly, form vertical cross partitions.

is glued to the underneath or White side of the longitudinal dividerpanel I6. (It is well understood that ordinary cardboard stock often Yhas a nished or white side ,and a. rougher gray side. In Fig. 2, the gray side is uppermost; when` theV blank is folded into aV finished carton, the white side is outward.) The side or edge of the. foldedg1ued`blank after panelZ is glued to panel I6 appears as shown in Fig. 3. Folding is done on lines h-h and y-i. Thereafter, the blank is folded on'linesc-c and e-e,l as illustratedin Fig. 4. Then the blank is foldedito bring the gray side ofv panel I8.v against the gray side of panel I2".` Glue indicated at win Fig. 4 is placed on panel I8 prior to folding, and the folded blank is pressed to'set the glue. The gluing operations are now complete, and the folded blank as shown in Fig. 5 is ready for shipment to the user.

The user, by pressing on opposite corners of the box (indicated at :z: and y in Fig. 5) with the fingers of one hand while raising the cover portion comprising panels I0 and I I with the other hand, causes the folded panels to separate as shown in Fig. 6 until the full open position is reached as shown in Fig. 7. At this stage, the end flaps are still open. End panels 2| and 22 are folded on lines lc-c and Z-Z, and the end tabs 2 are fitted into and locked in their respective locking slots 5. This is done by depressing the end-pieces 23-23 of the panels I5 and I9 and the four endmost lateral dividers 3 of panels l5 and I9 so that they are vertical, with their tip ends passing through the bottom slots 4. The end tabs are folded inwardly, both ends of the tabs being placed under the triangular portions 30 remaining in panels I5 and I9 when the dividers are cut, and one end of each tab being locked in a slot 5 when the divider bearing that slot is depressed. All of the remaining dividers will now be depressed to form a plurality of compartments, and the carton is ready for lling. When the carton is full, the cover is bent along fold line b-b and the cover brought down so that the tabs I are introduced into the container adjacent the forward wall. The cover is slightly displaced to the right in Fig. l in so d0- ing, and on returning to its natural position, the tips of the locking tabs are held under the triangular portions 30 (Fig. 10). Two of the tabs I are end reenforcing tabs Ia and Ib. When closing the box they slide straight past the end locking tabs 2 and brace them and the corners of the box as shown in Fig. 10. Each forward corner is thereby braced and reenorced.

The saving in material is believed to be due to the way the blank is folded so that the extreme G Ild panel fof the blank (panel 20) is secured to 3. a mid-portion of the box (panel I6) and the mid-portion of the blank (panel I8) is thereafter secured to the back Wall (panel l2). There is thus a very small amount of duplication of either walls or bottom. Protection oftthe bottoms of fragile articles is aorded inexpensively by the protruding vertical ends of the Vlateral dividers.

The back, ends and front (when the cover is closed) all have double thickness which provide strength and safety, but at small cost because of the small area involved. The triangular cornerbraces 30 provide strength, as Well as lockingm means. f

The one-piece construction simplifies manufacture and handling. The ease with which the" glued blank is made up intoa box promotes speed in packing. The finished carton is small and compact. The bottom projections, which furnish a safety feature, are an integral part of the box, and so do not tend to slip upwardly out of the slots 4. The form of double-locking used is insur-v half the width of the carton, a second gluing panel adapted to be secured to said back panel, and a second panel o1 vertical lateral dividers.

2. VA carton formed of a single piece of sheet stock having, on one end of said stock, a locking panel, in which some of the stock is cut away to provide locking tabs, and a series of panels secured thereto which comprise, in sequence, a cover panel, a back Wall panel, a bottom panel the width of the carton, a front Wall panel, a panel of vertical laterally extending dividers, a longitudinally extending vertical divider wall, a

second bottom panel which is approximately one- I .halfthe width of the carton, a gluing panel secured to said back panel, a second panel of vertical'laterally extending dividers, -and a second gluing strip secured to said longitudinally extending vertical divider wall.
